Güßgraben, Dry valley and ditch in Hettstadt, Germany.

Güßgraben is a dry valley and ditch system near Würzburg featuring natural valley formations combined with constructed drainage channels. This mix creates a landscape shaped by both geological processes and human water management efforts.

The Güßgraben begins near Gut Greußenheim as the Hirschlochgraben and runs south as the Holzbuchgraben and Fußgraben before turning west as the Güßgraben. It is a roughly 6 km long dry valley that empties into the Aalbach valley at Roßbrunn. The Aalbach itself approaches from the east, and the Güßgraben belongs to its river system.

The Güßgraben takes its name from the dry valley it runs through, which begins near Gut Greußenheim as the Hirschlochgraben and changes name along its course to Holzbuchgraben and Fußgraben before becoming the Güßgraben. It flows into the Aalbach valley at Roßbrunn, so the watercourse belongs to the Aalbach river system.

The Güßgraben runs about 6 km from near Gut Greußenheim southward, then west, meeting the Aalbach valley at Roßbrunn. It is a dry valley with no marked trailhead, so approach on foot from Hettstadt or Roßbrunn and follow the valley floor; the ground is uneven and weather-dependent.

The combination of natural dry valley and constructed ditch demonstrates how water management operates in this region. This dual-nature principle makes the location an example of adaptation to local soil conditions.
